Issues and Debates Flashcards
What are the features of free will?
- People play active role + consciously make choices about behaviour/thought
- Self-determining, active agents: responsible for behaviour independent of internal/external influences
- Free from causal influences of past events: impossible to predict behaviour (not compatible with science)
- Instead, psychology should study subjective experiences, not general laws
- Teleology (do something for a purpose)
What is an example of an approach which uses free will?
Humanistic approach: freedom necessary to achieve self-actualisation
What are the features of hard determinism?
- Free will is an illusion so behaviour/thoughts outside control
- Internal/external influences govern/control us
- Behaviour is predictable (compatible with science)
- Aetiology (explains causes)
What are the features of soft determinism?
- Behaviour/thoughts are to an extent governed by internal/external factors, but people still have some element of control
- Behaviour is predictable but not inevitable
What is an example of an approach which uses soft determinism?
Cognitive approach: We choose our own behaviours/thoughts, but these choices only operate within limits of our knowledge/ experiences (schema)
What are the 3 types of determinism?
Biological determinism
Environmental determinism
Psychic determinism
What is biological determinism?
Emphasises role of biological factors in controlling behaviour/ thoughts (biological approach)
- genes -> SERT in OCD
- neurochemistry -> high dopamine (attention + movement) in OCD
- brain structure -> caudate nucleus in OCD
- brain function -> autonomic NS in anxiety or stress
What is environmental determinism?
All behaviours controlled through conditioning; our experience of choice is the sum of reinforcement through life (behaviourist approach)
Skinner- free will is ‘an illusion’
Phobias acquired via classical and maintained via operant
What is ‘double’ determinism?
Interactions of biology (genotype) and environment (phenotype)
What is psychic determinism?
Behaviour controlled by unconscious conflicts repressed in childhood (psychodynamic approach)
- psychodynamic stages of development & fixations
- ‘slip of the tongue’ explained by influence of unconscious
What are 2 positive implications of taking a free will approach? (over determinism)
Important implications for mental health
- general laws underestimate the uniqueness of humans
- conscious reflection on own actions is seen as best way of achieving goals + learning from mistakes
- adolescents with strong degree of fatalism (external locus of control) = higher risk of depression
Believing + acknowledging free will has + impact on self
Consistent with society’s ideas of responsibility + self-control
- in law, offenders held responsible for their actions
- Mobley 1981 ‘born to kill’ due to family disposition: US court rejected argument
- hard determinism excuses behaviour, free will does not
Free will argument important in social and legal sense
What are 2 positive implications of taking a determinist approach? (over free will)
Helps establish psychology as a science
- looks for causes of behaviour (although unfalsifiable)
- general laws developed, meaning behaviour can be predicted -> RW application (eg: SSRIs)
Places psychology with established sciences so explanations for behaviour more valid + trusted, effective RW application in treatment
Can explain behaviour that undermines free will
- sz and OCD loss control over thoughts and behaviour
- people with disorders don’t consciously choose delusions/obsessions/ compulsions
- true as meds (eg: antipsychotics) alleviate symptoms
For mental illness, behaviour determined, gives patients certainty disorder not to own choosing
Why is the interactionist approach better than just free will or determinism?
Interactionist approach is best
- cognitive approach adopts soft determinism to explain behaviour
- we are ‘choosers’ of our own behaviour, but these choices are limited by what is known (schema determined by past experiences)
- CBT works by changing automatic, negative thoughts to more rational (can alleviate depression)
- SLT reciprocal determinism: environment influences you, and you influence environment around you, both impact each other via behaviours chosen to be performed
Human behaviour better explained + treated when considering the value of both free will and determinism
What are causal explanations?
Based on the scientific notion that behaviour is determined by internal and/or external factors (there is a cause-and-effect relationship)
What are the basic principles of science?
All events have a cause: the cause can be tested using empirical methods (experiments)
IV manipulated + EVs controlled + DV objectively measured to establish causal relationship
Causes of behaviour then explained using general laws/theories
Formulation of laws allows for prediction + control (prevention/treatment) of behaviour
Is psychology a science?
For most approaches, psychology is a science (uses OTHER), some more deterministic than others (hard vs soft)
For the humanistic approach… scientific method not appropriate for studying complex human consciousness/experience
Humans are subjective in thinking/behaving due to free will
Free will inconsistent with aims of science
What 2 words are linked with free will/determinism debate?
Predictable / unpredictable
Inevitable / not inevitable
What is the motto of the holistic approach?
Whole > than the sum of the parts
What does the holistic approach suggest?
Human behaviour considered as a whole, integrated, indivisible experience
-> Behaviour is complex and whole system cannot be understood from just knowing individual components
Emergent properties arise from collaborative functioning of system, but doesn’t belong to any one part, only when system works as a whole
Give an example of an emergent property in psychology
Human consciousness is an emergent property of brain, not down to single neuron, but interconnections of neurons in nervous system generates complex human emotions eg: fear
Which approaches use holism?
Humanistic
Social psychology
What is the motto of the reductionist approach?
System = sum of parts
What is the scientific principle that underlines the reductionist approach?
Parsimony
Complex phenomena should be explained in simplest terms possible as less assumptions are made -> explanation more likely
Human behaviour should + can be understood by breaking systems down into smaller component parts
What are the 2 types of reductionism? Are they compatible with science?
Biological reductionism
Environmental reductionism
Both compatible with science as behaviour tested empirically and measured objectively
What is biological reductionism?
We are biological organisms, so behaviour reduced to physical/ biological level, explained through neurochemistry/ physiology/ genes/ evolution
Give an example of biological reductionism
Schizophrenia from dysfunctional levels of serotonin
What is environmental reductionism?
Complex behaviours reduced to series of S-R chains that come about through conditioning
Give an example of environmental reductionism
Phobias acquired via classical conditioning, maintained via operant conditioning
What does levels of explanation mean?
Which level is appropriate to explain human behaviour
What are the 3 levels of explanation with examples from schizophrenia?
What are 2 strengths of holism?
Some behaviours only understood at higher level
- due to some behaviours only emerging in group context, cannot be understood at individual level of group members
- eg: Stanford prison experiment not understood by observing participants as individuals, as all had satisfactory health checks
- was understood by interaction between people and the group
- quality of feelings only understood from subjective interpretation
- eg: thinking about colour blue/red involved same region in brain, but feelings experienced are different -> not explained by reductionist
Higher level analysis useful as provides more valid account of subjective human behaviour
Doesn’t oversimplify behaviours
- removing social context may result in inaccurate conclusions about the behaviour as social context often important in understanding intention behind the behaviour
- eg: pointing a finger follows same physiological pattern regardless of intention, but social context allows understanding of why eg: drawing attention, aggression
Holism can fully explain behaviour, not just part of explanation
What are 2 strengths of reductionism?
Has more widespread practical value
- holism suggests that eg: depression caused by many factors -> hard to know which is most influential, and thus which to prioritise for therapy
- but by breaking disorders down, can empirically test effectiveness of drug therapy (SSRIs)
By identifying most influential cause of behaviour, reductionism can provide treatments that are more useful to a wider range of people
Scientific basis to research
- focus on empiricism and objectivity
- to test hypothesis, behaviour broken down into parts, allows for operationalisation of variables
- can establish causal relationships
- eg: Strange situation operationalised component behaviours such as separation anxiety
Reductionist approach increases credibility of psychology as a science
Why is the interactionist approach better than just holism or just reductionism?
Considers how several levels of explanation interact to explain a behaviour
- eg: MAOA-L variant and abusive childhood → aggression
By considering interaction of dif levels, more effective treatments/interventions offered
What does the nature-nuture debate look at?
As behaviour lies on a continuum between nature and nurture, both necessary to explain behaviour
Looks at relative contribution of nature/nurture on a particular behaviour
Outline the nature argument
Based on nativism: all human characteristics are hereditary
Which approach is PRIMARILY nature?
Biological approach
Behaviour + thinking is result of innate biological systems -> although does consider environmental influences (phenotype)
Outline the nurture argument
Based on empiricism, mind is a blank slate and behaviour is result of environmental learning
Dif levels of the environment -> pre-natal (eg smoking, music) post-natal (eg social conditions)
